A Mayo woman held a vigil outside the courthouse in Castlebar yesterday calling for the seal to be lifted on documents relating to Mother and Baby Homes.
Grainne De Barra ran as a candidate in the General election and she came out in protest of the legislation, which was signed into law at the weekend.
The bill see a database gathered by the Mother and Baby Homes Commission sent to Tusla, and will leave the rest in the custody of the Department of Children.
Archives and survivor testimony, gathered by the commission investigating the homes, will be sealed for 30 years under legislation from 2004.
Meanwhile, Minister for Children Roderic O'Gorman said the question of access to records will be decided at a future date after refusing to accept a series of opposition amendments to the bill.
Grainne De Barra told Midwest News that survivors of these institutions should have the right to receive their information.
